To all whom t may concern.'

Be it known that l, RAY P.' lDnanY, a citizen of the United States,residing at 22 Parkside, Upper Montclair, in the county of Essex andState ot' `New Jersey, have invented certain new and useful improvementsin Floor Coverings, of which the following is a. specification.

rilhis invention relates to floor coverings such as the class of floorcoverings designated under the trade name congoleumfl etc. Such floorcoverings generally consist of a layer of bituminous lmaterial one sideof which is covered with a printeddesign to simulate the appearance ofprinted, inlaid or other linoleum, and the other side of which isgenerally covered with a one-tone pigment.

lt has been found a disadvantage in connection with this class of floorcoverings, especially w'hen such coverings are used in small form tocover merely a portion of the floor, and are not fastened inA any wayyto such floor, that the iloor covering slips about and does not remainin position. Such coverings, moreover, are not generally good heatinsulators, heat insulation beingdeerned desirable in order to store theheat values within the compartment on the floor of which the covering isplaced.

rlhe floor covering of my invention possesses the desirable propertiesof affording superior heat insulation and of being soconstructed thatthe covering has a better grip or purchase .on the floor than thecoverings previously in use.. Furthermore, by my construction, the floorcovering has a springy or carpety feel under 'the feet, and has otherdesirable properties subsequently to be enumerated.

Referring to the drawing wherein l have illustrated one embodiment 'ofmy invention,

Fig. l shows in cross-section the floor covering of my invention, and

Fig. 2 shows in elevation the bottom surt'ace of the floor covering.

Fig. 8 shows in cross-section a modifica tion of my invention.

l indicates the main body portion of the floor covering consisting, torexample, ot a sheet of bituminous material A, the upper surface 2 ofwhich is covered with pigment in imitation of printed or inlaidlinoleum,

or other floor covering.I The under surface of the iloor covering iscovered by a layer 3 tions of the areas covered by the ribs and the idepressions may be varied considerably while still retaining theprincipal advantages oi" my construction. While the ribs are shown intwo series at right angles to each other, equally spaced and parallellyarranged, th-e ribs may be otherwise arranged and still preserve theadvantages of my invention.

ln order to realize the best results, the ribs should be spaced a smalltraction of an inch apart, generally less than one quarter ot an inch.llVhile various types ot cross- -sectional character may be used withadvantage, l prefer to use either the rectangular ribs shown in Figs. land 2, or a triangular rib as shown in Fig. 3. As illustrated in thisligure of the drawing, the body portion l' ot the sheet A has the uppersurface thereof covered with pigment 2', while the lower surface iscovered by a layer 3 ot pigment or similar material, and is providedwith the intersecting ribs t deiining the depressions 5,

As a result of this construction., when the floor covering is applied tothe floor or other surface whereon the Same is to be used, there isprovided between the Hoor and the under surface of the covering aplurality orp aircells 5 serving to increase the heat insulating valueof the ioor covering. Further more the ribs 4, being of rather smalldimension, are comparatively compressible and serve, therefore, toimpart to the iioor covering a certain springy or carpety teeling whentrod upon. The ribs also serve the added function of gripping the floorbetter than a cover with the under side smooth would do. As furtheradvantages following from this type of construction, l have found frompersonal experience that such a floor covering has great flexibility andelasticity, and does not crack or break as easily when provided withsuch ribs as when it is withles out them. Furthermore, when the floorcover1ng 1s stored 1n rolls, the depresswns 1n the same serve to retainsullieient air to cause 4the necessary oxidation of the oils in thecovof Well-defined ribs on the other side of the said sheet.

3. A flexible composition floor Covering comprising a sheet ofbituminous material, a covering of pigment in the form of a design onone side of the said sheet, and a plurality of Well-defined intersectingribs on'the other side of the said sheet.

4. A flexible floor covering comprising a sheet of bituminous material,a covering of pigment in the form of a design on one. side of the saidsheet, and a plurality of Well-defined, intersecting ribs on the otherside of the said sheet and integral with the same.

In testimony whereof I ax my signature.
